Sorry for late answer, I'm sooo la... ehm busy.
My suggestion is to try out QXDM... because Modem is AMSS -> this is Qualcomm part. Here some instructions for activate Qualcomm port:

At the moment, unsure if something is written here on XDA:

Thanks. Oleg already tried to play with it, no interesting result though.
I really need lowest level debug logs (so with debug level set to highest) from early Nucleus init stage, do you know how to obtain these?
I do believe it can be UART output from bada, but how to enable it? In fact Nucleus doesn't print any messages to my UART. :/
These logs should contain similiar strings for eg.
DRV_Device_Init...: hwrev =
DRV_Device_Init...: wCPbootloader_status =
(this one below during audio cable put in/out)
DRV_int_earjack35_dt_handler in Event, param =
(this one below during screen framebuffer init)
screen width=%d height=%d va=0x%x pa=0x%x
(this one below is one of many during modem booting - thats exactly what I am interested about)
DRV_Send_AMSSRunReq!!!!!!!!!!!!!!!!!
Else, these logs may be called "Mocha log"
(Mocha seems to be codename for process similiar to Android's zygote)
Also, there are various debuglevels, did you meet any of these?
ModemDebugLevel
CameraDebugLevel
SessionDebugLevel
StatsDebugLevel
MobileLevelDebugLevel
DebugMsgDebugLevel
LoggingMode (!)
And a lot more.
Or, maybe it is possible to get these logs by WinComm method described by adfree? (I still can't get it working on my S8530)
Did you tried "Help" command there? Should print alot of interesting things, like these I'm attaching (together with some mess and their descriptions, straight from IDA).
There is much, much more.
